STOVE.

SPECIFICATION forming part of Letters Patent to. 622,951, dated April 11, 1899.

Application filed January 3, 1898.

To (all whom, it may concern.-

Be it known that LHENRY I-LHERRENDEEN, a citizen of the United States,residing at the city of Big Rapids, in the county of Mecosta and Stateof Michigan, have invented certain new and useful Improvements inStoves, of which the following is a specification.

This invention relates to certain new and useful improvements in stoves,and is peculiarly adapted to that class of stoves known as air-tightstoves, the stove being adapted for use of either coal or wood; and theinvention consists in combining a drum with a stove-body, said drumbeing provided with a ventilatingpipe adapted to take the air from apoint near the floor and conduct the same directly into the drum.

It also relates to the combination of the drum, the ventilating-pipe,the stove, and a draft-pipe connecting the ventilating-pipe with thestove and adapted to be used as a direct draft.

The objects of the invention are, first, to produce a superiorheating-stove, thereby saving fuel; second, to produce a perfectventilating-stove adapted to carry off all the gases when the directdraft is closed and the door of the stove closed; third, to prevent thecollection of creosote, which is peculiarly liable to collect in whatare known as air-tight stoves; fourth, to prevent the collection ofgases, and thereby prevent the explosion of the same, which frequentlyoccurs, and, fifth, to provide ventilating-fines adapted to carry offthe smoke and gases when the stove is open ed. These objects Iaccomplish by means of the mechanism illustrated in the accompanyingdrawings, in which Figure 1 shows a side elevation of my improved stove,together with the drum, ventilating-pipe, and draft-pipe and Fig.2 showsa vertical sectional view through the center of the drum, the draft andventilating pipe, and the stove.

Similar letters refer to similar parts throughout both Views.

A represents the drum, which is mounted upon the stove, and in theexample of my invention shown in the drawings directly above it. Thisdrum is connected to the stove by means of the fines H H, &c. In thedrawings I have shown six of these connecting-fines;

Serial No. 665,263. (No model.)

the floor (shown by D) extending upward and opening into the drumpreferably at a point near the center thereof, as shown in Figs. 1 and2. Instead of the openings D any other form of openings may be used, orthe head or lower end of the ventilating-pipe C may be raised a shortdistance above the floor for the purpose of receiving the air at itsbottom and conveying the same directly into the drum A.

I represents the draft-pipe, which is preferably placed on the body ofthe stove B at a point opposite the door J.

E represents a damper which I call the draft-damper, placed in the pipeI and adapted to either entirely or partially close the opening throughthe pipe Ito the pipe C.

F represents a damper which I denominate the ventilating-damper, placedin the pipe 0, preferably at a point near the upper part of the body ofthe stove. The particular locationof the damper F, however, is notmaterial, only that it be placed in the pipe 0 above the entrance of thepipe I.

The door J is intended to shut, so as to make the bodyof the stovesubstantially airtight. It is supported on hinges in the ordinary mannerand provided with a catch to hold it when closed.

The arrows in the ventilating-pipe 0 show the movement of the air whenit is taken from the point near the floor and conveyed directly into thedrum. The arrow in the pipe Ishows the direction of the air-current whenthe ventilating-damper F is closed. When the ventilating-damper F isclosed and the ventilating-damper E is opened, the draft is takenthrough the openings D, conveyed in the ventilating-pipe O, and fromthence through the draft-pipe I into the stove. Thus it will be noticedthat the air or oxygen which is taken into the stove for the purpose ofsupporting combustion is not taken in on the side of the stove where thedoor is situated, but on the opposite side thereof, or at least at apoint some distance from that at'which the door is situated.

In air-tight stoves when the door is closed and the draft is shut off bythe damper in the pipe, ,as is ordinarily done, the gases bearingcreosote gather in the upper part of the stove or in the drum in case adrum is used; but in the construction shown in the drawings anddescribed in this specification the openings through thelflues H intothe drum and from the drum through the stovepipe will always carry offthe gases, and thereby prevent the gathering of combustible gases in thestove, and also prevent the deposit of creosote either in the stove,drum, or pipe. The arrangement of the Hues, as above described, willcause a strong draft when the door is opened,

so that the smoke and gases will immediately I be carried through thedrum into the stovepipe, and from thence into the open air, there beingno back pressure and no tendency for smoke to escape through the door.

The arrangement of the draft through the pipes O and I, which furnishesa sufficient amount of oxygen for combustion, permits the stove to beclosed, so as to be practically airtight, the dampers being soconstructed as to close, when turned into a perpendicular posi tion or aposition at right angles to the pipe I, the entire opening through thepipe 1.

Having thus described my invention, what I claim to have invented, anddesire to secure by Letters Patent, is

l. The combination with a portable stove, of a heating-drum arrangedabove the stove and connected to the latter by a plurality of flues andhaving a stovepipe, and a ventilating-pipe having its inlet end arrangednear 2. The combination with a portable stove, of a heating-drumarranged above the stove and connected to the latter by a plurality offiues and having a stovepipe, a ventilatingpipe having its inlet endarranged near the floor and connected at its upper end directly with theheating-drum, and a draft-pipe connecting the lower portion of theventilatingpipe to the lower portion of the combustionchainher of thestove, substantially as described.

3. The combination with a portable stove, of a heating-drum arrangedabove the stove and connected to the latter by a plurality of flues andhaving a stovepipe, a ventilatingpipe having its inlet end arranged nearthe floor and connected at its upper end directly with the heating-drum,a draft-pipe connecting the lower portion of the ventilating-pipe to thelower portion of the combustion-chamber of the stove, a damper arrangedin the draft-pipe, and a damper arranged in the ventilating-pipe abovethe draft-pipe, substantially asdescribed.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
